STUD.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed August 13, 1904, Serial No- 220,67l. Renewed December 13, 1906. Serial No. 347,693.

To all whom it may concern:

Be it known that I, .IosEPn LIZOTTE, a citizen of the United States, and a resident of Quincy, county of Norfolk, and State of Massachusetts, have invented an Improvement in Studs, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. V

The present invention relates to a stud, or similar article, and is embodied in a celluloid covered metallic stud, the purpose of the invention being to obtain a durable covered stud with the use of a minimum amount of covering material. Furthermore, the me tallic portion of the stud embodying the invention may be of the usual shape, no special configuration being necessary to keep the covering material in place.

The metallic portion of the stud may be made in any suitable or usual way and of any suitable or usual form, the celluloid covering being in the nature of a veneer, the surface of the stud being covered with a comparatively thin layer of celluloid of substantially uniform thickness, the said layer being held in place by turning or crimping the edge thereof under the surface of the stud. In producing the stud, 1 take a piece of sheet celluloid substantially the same in shape as the shape of the top of the stud, but somewhat larger in diameter, and heat the celluloid sufficiently to render the same pliable, it being unnecessary to bring it into a fully plastic condition. In such pliable state, the sheet of celluloid is made to conform and adhere to the surface of the stud, and the edges of the sheet of celluloid are then crimped in under the edge of the top of the stud so that the celluloid veneer is firmly held upon the stud as soon as the celluloid has cooled and hardened.

Figure 1 is a vertical section, on an enlarged scale, of a lacing stud embodying the invention. Fig. 2 is a plan view of a piece of the sheet celluloid which is used in covering the stud and Fig. 3 is a vertical section, similar to Fig. 1, showing the stud partially finished.

Referring to Fig. 1, the stud is provided with the hollow shank a, and a head portion a or stud proper, which may be of any suitable or usual construction, any ordinary metallic stud or eyelet being capable of being covered in accordance with the invention. For illustration, I have selected a lacing-stud of the kind comrnonly used with shoes or gloves, The celluloid covering consists of a layer of sheet celluloid b which may be uniform in thickness, and merely of sufficient thickness to form a veneer which covers and protects the metal surface of the stud. In applying the sheet of celluloid b, I use a moderate degree of heat which is sufiicient to render the sheet of celluloid pliable, it being unnecessary to melt the same or to reduce it to a fully plastic condition, and, when thus heated, the sheet is pressed on the top of the head portion a the edge of the piece of celluloid projecting beyond the edge of the said head portion, since the piece of celluloid is larger in diameter than that of the head portion. While the celluloid remains in its pliable condition, the overlying edge thereof is turned or crimped under the periphery of the head portion, as indicated in dotted lines, Fig. 3 and when the shank of the stud extends from the periphery of the head, as in the example shown, the part of the celluloid which overlies the shank is pressed towards the same and thinned down.

The studs embodying the invention are very durable, and, at the same time, contain much less celluloid than the studs with'molded celluloid heads now commonly in use. Furthermore, since the small sheets of celluloid, adapted for the individual studs, are cut from a sheet of celluloid when cold, the waste material is of greater value than the waste material after it has been melted or reduced to a plastic condition. Furthermore, there is no necessity of trimming or finishing the studs after the celluloid has been applied, since the edge of the celluloid sheet is pressed against the convex under surface of the stud where it is out of the way of the lace.

What I claim is:

A stud, the head portion of which has a concave under surface and a thin sheet or veneer of celluloid overlying and being in contact with the head of the stud and extending around the edge thereof into contact with said concave under surface for some distance beyond said edge.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
